Details please. Does the printer refuse to print, or does the operating system printing subsystem refuse to print? What is your operating system? Have you given Brother support an opportunity to respond?
Printer toner indicator says Black is almost full (recently changed as I print mainly b/w), Cyan & Magenta are low, Yellow is empty and the one it complains about when trying to print.
I've continued messing with it for the last hour and even putting the printer into "black and white" mode, and changing the printer options in the OS to "Mono" it still refuses to print. Brothers own help page says it works [0], but I've followed these and it still doesn't print.
I've tried resetting the printer, updating the firmware and drivers, rebooting both printer and computer.
